What is the percentage of water in the hydrate CoCl2 • 6H2O? Show your work.
Lelu [443]
Hello!

First you have to find the molar mass of the molecules

C = 12
O = 16
2Cl = 71
6H2O = 108

Add them up to find the total molar mass

12 + 16 + 71 + 108 = 207g/mol

Divide the amount of water by the total molar mass

108 / 207 = 0.5217

Convert this to a decimal

0.5217 = 52.17%

The answer is 52.17%

Hope this helps!

If 1.00 L of gas at 1.00 atm of pressure is compressed to a volume of 0.473 L, what is the new pressure of the gas?
natima [27]

Answer:

2.114 atm

Explanation:

Since it is just pressure and volume, use Boyle's Law

P1V1 = P2V2

Then plug in numbers

(1 atm)(1 L) = P2(.473 L)

P2 = 2.114 atm

How do I find the rate of reaction on a graph
Nonamiya [84]

Rate of reaction can be understood as the rate of change of the materials, such as the rate of depletion of the reactants or the rate of production of products.  Therefore, if a graph of concentration and time is plotted, the rate of reaction is simply the slope of the graph.
