The pressure exerted by 0.57 moles of CO2 at a temperature of 25°C and a volume of 500 ml is 28 atm.

<u>Explanation:</u>

According to ideal gas law,

PV = nRT

where P represents the pressure of a gas,

V represents the volume of a gas,

n represents the number of moles,

R represents the gas constant = 0.0821 L atm / mol K.

T represents the temperature of a gas.

Given V = 500 ml = 0.5 l, T = 25°C = 298 K, n = 0.57 mol

PV = nRT

P = nRT / V

= (0.57 $\times$ 0.0821 $\times$ 298) / 0.5

P = 28 atm.

The pressure of a gas is 28 atm.

A certain compound contains 4.0 g of calcium and 7.1 g of chlorine. Its relative molecular mass is 111. Find its empirical and m

Phantasy [73]

Given :

A certain compound contains 4.0 g of calcium and 7.1 g of chlorine.

Its relative molecular mass is 111.

To Find :

Its empirical and molecular formulas.

Solution :

Moles of calcium , $n_1=\dfrac{4}{40}=0.1\ moles$ .

Moles of chlorine , $n_2=\dfrac{7.1}{35.45}=0.2\ moles$ .

The ratio calcium and chlorine is 1 : 2 .

So , the empirical formula is $CaCl_2$ .

Now , molecular mass of $CaCl_2$ is :

$M=40+(2\times 35.45)\\\\M=110.9\ g$

So , $n=\dfrac{111}{110.9} \approx1$

Therefore , the molecular formula is also $CaCl_2$ .

Hence , this is the required solution .

A student must make a 3 m acid solution using a 5 m acid solution. which of these is the safest way to make the solution?

weqwewe [10]

The motivation to abstain from adding water to concentrated acids is that, with a few acids, amid weakening, a considerable measure of warmth is discharged, by adding the corrosive to the water, the generally extensive measure of water will retain the warmth. On the off chance that you added water to concentrated corrosive when you initially beginning pouring the water, it could get sufficiently hot for the little measure of water that was filled all of a sudden bubble and splatter corrosive on you. Concentrated sulfuric corrosive is most famous for doing this, not all acids get that hot on weakening, but rather in the event that you make a propensity for continually adding the corrosive to water for every one of them, you can't turn out badly.
