How to Calculate Moles from Molecular Weight Updated April 24, 2017 By Kristen May Ounces and grams are two common units used to measure weights in small quantities. Ounces commonly are used in the United States, where the main unit of measurement for weights is the pound. An ounce is 1/...
Grams to Moles Step 1 Find the number of gramsof the substance. You will know from the problem how many grams and what the substance is, for example, 12 g of water. Step 2 Find the molecular weight of each atom in the substance. The molecular weight is how much each molecule of the...

Molarity (M) = (moles of solute) ÷ (liters of solution). To calculate the number of moles of a solute, you need two pieces of information, which you may have to infer from other data. The first is the chemical formula of the solute, and the second is the mass of the solute. Yo...

If you use the ideal gas law (and I can't think of any gases that I've come across that vary significantly from ideal gas behavior at one atmosphere and 60F), you will determine the number of moles per time. Multiply by the molecular weight and you have mass per time. The actual ...
To calculate the freezing point of a solution containing 60 g of glucose in 250 g of water, we can follow these steps:Step 1: Calculate the number of moles of glucose To find the number of moles of glucose, we use the formula:
A solution is prepared by adding 0.002 moles of sodium acetate to a 100 ml of 0.03 M acetic acid. K_a(CH_3COOH)= 0.000018. (a) Assuming that no volume change occurs upon addition of the sodium acetate what is the pH of the solution? (b) What is the con...
