Molar mass :

H_2SO_4= 1*2+32+16*4= 98g/mol

Number of moles:

n =  \frac{solute}{molar( mass)}

n =  \frac{73.5g}{98g/mol}

n=0.75 (moles)

Volume = 3.0 L

M =  \frac{n}{V}

M =  \frac{0.75(moles)}{3.0L}

M = 0.25 mol/L ^{-1}

hope this helps!

Which formula equation represents the burning of sulfur to produce sulfur dioxide?
Leni [432]

Answer:

S(s) + O2(g) --> SO2(g)

Upper S (s) plus upper O subscript 2 (g) right arrow with delta above upper S upper O subscript 2 (g).

Explanation:

The reaction is given as;

Sulfur + oxygen --> Sulphur dioxide

Sulphur = S

Oxygen = O2

Sulfur dioxide = SO2

So we have;

S(s) + O2(g) --> SO2(g)

The crrect option is option A. Upper S (s) plus upper O subscript 2 (g) right arrow with delta above upper S upper O subscript 2 (g).
