Answer
The mass of sodium hydroxide in 40 cm³ is
grams.
Explanation
## Step 1: First, we need to convert the volume from cm³ to dm³, because the given concentration is in grams per dm³. We know that 1 dm³ = 1000 cm³.## Step 2: Next, we use the formula for calculating the mass of a substance in a solution, which is: mass = concentration x volume. ### The formula is:
## Step 3: Substitute the given values into the formula. The concentration is 80 grams per dm³ and the volume is 0.04 dm³ (40 cm³ converted to dm³).
