Answer:
The answer is
<h2>34.02 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of lead = 3 mL
density = 11.34 g/mL
The mass of the lead is
mass = 3 × 11.34
We have the final answer as
<h3>34.02 g</h3>
Hope this helps you
Answer:
No.
Explanation:
This is because a solution is a mixture with two substances that have already dissolved in each other and so there is no residue left. Filtration works such that part of the mixture has smaller particles that can pass through the membrane of the filter paper while the bigger particles get stuck onto the paper as residue. A solution has a uniform size particle throughout and thus filtration does not work for purifying a solution.
Answer:
moles in 0.250 g of h20 is 1.349x10^-2
Answer: mass m = M·c·V
Explanation: M(CaCl2) = 110.98 g/mol, c= 0.15 mol/l,
n=m/M= cV, volume of Solution is not mentioned
