![]() The molar mass of KClO3 is 122.548 g/mol. ![]() Problem: Convert 2.50 moles of KClO3 to grams. The number of moles of KMnO4 will be 0.158Īnd here is how you should enter this problem into the calculator above: grams to moles problem solution Moles to grams example problem Divide the given mass (25.0 g) by the molar mass (158.032 g/mol) to get the moles.The molar mass of KMnO4 is 158.032 g/mol. Problem: Convert 25.0 grams of KMnO4 to moles.įind out the molar mass of the substance (hint: you can use Molar mass of the substance alone to calculate molar mass). Multiplying by the molar mass constant ensures that the calculation is dimensionally correct: standard relative atomic masses are dimensionless quantities (i.e., pure numbers), whereas molar masses have units (in this case, grams/mole).Īnd this is where our grams to moles/moles to grams calculator shines, thanks to our other calculator - Molar mass of the substance, which calculates molar mass for a substance given the formula.Īll you need to do is correctly enter your formula, choose whether you want a conversion from grams to moles or a conversion from moles to grams, and, in case of g to mol, enter the mass, or, in case of mol to g, enter the moles. The molar mass of a compound is given by the sum of the standard atomic weight (namely, the standard relative atomic mass) of the atoms which form the compound multiplied by the molar mass constant. The molar mass of atoms of an element is given by the standard relative atomic mass of the element multiplied by the molar mass constant, 1 × 10−3 kg/mol = 1 g/mol. The molar mass is a physical property defined as the mass of a given substance (chemical element or chemical compound) divided by the amount of substance. You need to multiply the molar mass of the substance by the number of moles:Īs you can see, the most difficult task here is finding out the molar mass of the substance. You need to divide the mass of the substance by the molar mass of the substance: #Chemistry calculator scientific notation how tomolar mass of the substance in grams/mole How to convert grams to moles? = 0.3 x 10 -6 (moved the decimal point to the left one time.There is a simple relation between grams and moles: Converting 3.0 x 10 -7 in engineering notation: Converting 3.5 x 10 6 in engineering notation: = 10 x 10 3 (moved the decimal point one place to the right)Ģ. Converting 1.0 x 10 4 in engineering notation: How to represent the following numbers in engineering notation?ġ. ![]() The rule is that the power of 10 must be a multiple of 3. But there is a rule that separates engineering notation from scientific notation. Scientific notation is also similar to engineering notation. Scientific notation to engineering notation: But in some regions, standard form means the real number form.ĭepending on the number system you are using, leave the scientific notation or convert it into the real number form (decimals). Scientific notation is also referred to as standard form in the UK number system. To perform arithmetic operations on scientific notations, use our scientific notation calculator. This means we have to move the decimal point three times to the left. If the power is positive, move to the right, and if the power is a negative move to the left. The direction of movement of the decimal point depends on the nature of the power of 10. Meaning here is if the power of 10 is 3, move the decimal point to the right 3 times. Move the decimal point to the left or right equal to the power of 10 times. ![]() To write scientific notation in other forms, you can use the calculator above. The power of 10 can be positive or negative depending on the nature of the number. There is always a 10, raised to some power, involved in it. The numbers in the example above are in scientific notation. It is a way of writing numbers such that the number is greater than or equal to 1 and smaller than 10. ![]() Scientific notation is a representation of large or small numbers used in numerical and other scientific calculations. This scientific notation calculator is used to convert scientific notation to other representations of numbers like engineering notation, decimal, and standard form. ![]()
