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!

What is the initial temperature (in Celsius) of a 675 ml balloon if the
RoseWind [281]

Answer: 127 (3.s.f)

Explanation:

Boyle's law states that Volume x pressure = constant

Therefore let's first find the constant: 45 x 1900 = 85500

Then lets plug 675 ml and 85500 into the equation above:

675 x C = 85500

C = 127 (3 s.f.)
