Molar mass of NaOH is 40g/mole

Since you are given 0.10 moles of NaOH you will use this number to convert from moles to grams by using the molar mass. Here’s how it is done.

You must use a conversion factor and you already found one! 40g of NaOH per mole. So

0.10 mole NaOH = 40g NaOH = 4 g NaOH
—————-
1 mole NaOH


(The top is multiplied straight across and the bottom is also multiplied straight across, then the top and bottom is divided in the end to get 4g of NaOH)

How many moles of HCl are in 30.00mL of a 0.1000M HCl solution? A. 0.003000mol. B. 300.0mol C. 0.03000mol D. 3.000mol
Katyanochek1 [597]

Given the volume of HCl solution = 30.00 mL

Molarity of HCl solution = 0.1000 M

Molarity, moles and volume are related by the equation:

Molarity = \frac{Moles of solute}{Volume of solution (L)}

Converting volume of HCl from mL to L:

30.00 mL * \frac{1 L}{1000mL}=0.030000 L

Calculating moles of HCl from volume in L and molarity:

0.03000 L * \frac{0.1000mol}{L}= 0.003000 mol HCl

The final moles would be reported to 4 sig figs. So the correct answer will be 0.03000 mol HCl

Correct option: C. 0.03000mol
