Mass of sulphuric acid in 250 cm
Answers
GPT 3.5
To calculate the mass of sulfuric acid in 250 cm^3, we need to know the concentration of the sulfuric acid. Let's assume the concentration is 1M (1 mole per liter).
First, calculate the number of moles of sulfuric acid in 250 cm^3:
1M = 1 mole/L
250 cm^3 = 0.25 L (since 1 L = 1000 cm^3)
Number of moles = concentration x volume
Number of moles = 1 x 0.25 = 0.25 moles
Next, calculate the molar mass of sulfuric acid (H2SO4) which is:
2(1.01) + 32.07 + 4(16) = 98.09 g/mol
Finally, calculate the mass of sulfuric acid in 250 cm^3 using the number of moles and molar mass:
Mass = number of moles x molar mass
Mass = 0.25 moles x 98.09 g/mol = 24.52 g
Therefore, the mass of sulfuric acid in 250 cm^3 is 24.52 grams.
