## How many moles are in NaOH?

Determining the Molar Mass of a Compound

The molar mass of the compound NaOH is 40 g/mol.

## How many grams of NaOH are there in 500.0 mL of a 0.175 M NaOH solution?

Under 4.0⋅g of sodium hydroxide.

## How many moles of NaOH are contained in 65.0 mL?

M meaning our molarity, n meaning our moles involved, and v meaning our volume in Liters. n=. 143 moles.

## How many grams of NaOH are in 3 moles of NaOH?

A 3.0 M solution of NaOH has 3.0 moles of NaOH per liter of solution. There are 0.25 L of solution (250mL⋅1L1000mL) , so there are 0.25L⋅3.0mol/L=0.75mol of NaOH. The molar mass of NaOH is 40.0 g/mol, so there are 0.75mol⋅40.0g/mol=30g of NaOH, 30.

## How many moles are there in 20g of NaOH?

Number of moles which make up 20 grams of NaOH = (20 grams × 1 Mole)/(40 grams) = 0.5 moles.

## How many moles of NaOH are contained in 30ml of its 0.15 M solution?

= 0.15 / 1000 X 27 moles. = 0.004 Moles.

## How many moles of Ch₃oh are there in 150.0 mL of 0.275 M Ch₃oh?

The are ≈ 0.0428 moles of CH₃OH in 150.0 mL of 0.285 M CH₃OH.

## How many moles of NaOH are there in 225.0 mL of 2.50 M NaOH?

Hence, n = 2.50 / 0.225L = 11.111 moles.
