Question

Berapa molaritas larutan asam sulfat 95% dengan massa jenis 1, 2 gr/mL^-1? (Mr H2SO4 = 98) tolong jawab yaaaa

Answer 1

%berat = 95 %
Dari pernyataan iti dapat diketahui
* masaa H2SO4 = 95 gram
* massa air = 100-95 = 5 gram

ρ = m/v
1,2 = 5 /V
V = 5/1.2 = 4.17 ml = 4.2 ml

M = gr/Mr 1000/V = 95/98 1000/4,2 = 230,8 M
