Question

How many grams of H2So4 are contained in
0.05 litres of 0.5 M solution?​

Answer 1

Answer:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

Molarity=\frac{moles}{\text {Volume in L}}

0.5M=\frac{moles}{\text {0.05L}}

moles of H_2SO_4=0.025moles

Mass of H_2SO_4=moles\times {\text {molar mass}}=0.025moles\times 98grams/mol=2.45grams

Thus 2.45 grams of  H_2SO_4 are contained in 0.05 L of 0.5 M solution.

Answer 2

Answer:

2.45 gram of H2o4 are contained in 0.05 litres of 0.5 M
