Question

If the density of a solution is 3.12 g mL-1, the mass of 1.5 mL solution in significant figures is. (A) 4.7 g (B) 4680× 10-3 g (C) 4.680 g (D) 46.80 g

Tardigrade Admin · Accepted Answer

Density =( textMass/ textVolume) ∴ Mass = Density × Volume = 3.12 g mL-1 × 1.5 mL = 4.68 g = 4.7 g

Q. If the density of a solution is $3.12 g m L^{- 1}$ , the mass of $1.5 m L$ solution in significant figures is_______.

$4.7 g$

$4680 \times 1 0^{- 3} g$

$4.680 g$

$46.80 g$

Density $= \frac{Mass}{Volume}$
$∴$ Mass = Density $\times$ Volume
$= 3.12 g m L^{- 1} \times 1.5 m L = 4.68 g = 4.7 g$

Q. If the density of a solution is 3.12gmL−1, the mass of 1.5mL solution in significant figures is_______.

4.7g

4680×10−3g

4.680g

46.80g
