Calculate the molar mass of sulfuric acid to two decimal places in units of grams per mole (g/mol). Show how you reached your answer.

98.09g/mol

Step-by-step explanation:

the molar mass of any compound is derived by the  multiplying the individual atomic masses of each of the elements present in the compound by the number of atoms each element has and then adding each of the values together

for H₂SO₄ (sulphuric acid)

elements present are hydrogen, sulphur and oxygen

atomic mass of hydrogen = 1.00784

atomic mass of sulphur =32.065

atomic mass of oxygen = 15.999

the acid contains 2 atoms of hydrogen, one atom of sulphur and 4 atoms of oxygen

∴molar mass of H₂SO₄ = (2 × atomic mass of hydrogen) + atomic mass of                    sulphur + (4 × atomic mass of oxygen)

= (2 × 1.00784) + 32.065 + (4 × 15.999)

= 2.01568 + 32.065 + 63.996

= 98.09g/mol

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.
