Answer:
0.090 moles
Step-by-step explanation:
The number of moles of sulfuric acid in 15.0 mL of 6 M H₂SO₄ can be calculated using the formula:
moles = concentration x volume
where concentration is in moles/liter and volume is in liters.
Since the volume of sulfuric acid is given in milliliters (15.0 mL), we first need to convert it to liters:
15.0 mL = 15.0 x 10^-3 L
Now, we can calculate the number of moles of sulfuric acid:
moles = 6 M x (15.0 x 10^-3 L) = 0.090 moles
So, 0.090 moles of sulfuric acid (6 M) are in 15.0 mL of 6 M H₂SO₄.
