So first find the volume
so 7.78g/ml and (3.7505 times 10^4) grams
therefor we dividde (3.7505 times 10^4) by 7.78 and get how many ml
the answer is 4820.69 ml
kL means kilo lieters
kilo=1000
kL=1000Liters
ml=milileters=1/1000 leiter
1000ml=1L
therfor
1kL=1000L
1000L=1000 times (1000ml)
1000L=1,000,000ml
1kL=1,000,000ml
so to convert to kL divide 4820.69 by 1,000,000
0.00482069
convert to scientifiic notation
4.8 times 10^-3
the answer is 4.8 times 10^-3 kL
D = m / V
3.26 = m / 0.313
m = 3.26 x 0.313
m = 1.02038 g
hope this helps!
