16 g/ml
<h3>Further explanation</h3>Given
mass = 32.40 g
volume = 2.0mL
Required
Density
Solution
Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
Density formula:
ρ = density
m = mass
v = volume
Input the value :
ρ = 32.40 g / 2.0 ml
ρ = 16.2 g/ml
Rules for division: The least number of significant figures in the problem determines the number of significant figures in the answer.
32.40 = 4 sig.fig
2.0 = 2 sig fig
The answer must be 2 sig fig
So the answer = 16 g/ml
Answer:
4.90 moles of will produce (9.8) moles of
,
(4.90) moles of and
(39.2) moles of
Explanation:
From the question we are told that
The number of moles of is
The formation reaction of is
From the reaction we see that
1 mole of is formed by 2 moles of
1 mole of
and 4
This implies that
4.90 moles of will produce (2 * 4.90) moles of
,
(1 * 4.90) moles of and
(8 * 4.90) moles of
So
4.90 moles of will produce (9.8) moles of
,
(4.90) moles of and
(39.2) moles of
