Question

How many grams are there in 0.250 moles of sodium hydroxide

Answer 1

Answer: The mass of sodium hydroxide is 10 grams.

Step-by-step explanation:

To calculate the mass of a substance, we use the equation to calculate the number of moles, we get:

`\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}`

We are given:

Moles of sodium hydroxide = 0.25 mol

Molar mass of sodium hydroxide = 40 g/mol

Putting values in above equation, we get:

`0.25=\frac{\text{Mass of sodium hydroxide}}{40g/mol}\\\\\text{Mass of sodium hydroxide}=10g`

Hence, the mass of sodium hydroxide is 10 grams.
