You are supposed to add 0.1 mol of a substance with molecular weight = 354.9 to 1 liter of water. How much should you add? Choose one.

The options are:

3.549 g
35.49 g
35.49 mg
0.1 g
0.1 mg

35.49

To determine how much of the substance you should add, we need to use the relationship between moles, molecular weight, and volume.

The molecular weight of the substance is given as 354.9 g/mol, and you want to add 0.1 mol of it to 1 liter of water.

To find the amount of substance in grams, we can use the formula:
Mass (g) = moles * molecular weight.

First, we need to calculate the mass of the substance:
Mass (g) = 0.1 mol * 354.9 g/mol = 35.49 g.

Therefore, you should add 35.49 grams of the substance to 1 liter of water.
