Using p1v1/t1=p2v2/t2
p1=50
p2=225
v1=400ml
v2=?
t1=-20=253k
t2=60=333k
50x400/253=225xv2/333
7.9=0.7xv2
v2=7.9/0.7
v2=11.3ml

Answer : The new volume of gas will be 117 ml.

Explanation:

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}

where,

P_1 = initial pressure of gas = 50 kPa

P_2 = final pressure of gas = 225 kPa

V_1 = initial volume of gas = 400 ml

V_2 = final volume of gas = ?

T_1 = initial temperature of gas = -20^0C=(-20+273)K=253K

T_2 = final temperature of gas =  60^0C=(60+273)K=333K

Now put all the given values in the above equation, we get the final pressure of gas.

\frac{50\times 400}{253K}=\frac{225\times V_2}{333K}

V_2=117ml

Therefore, the new volume of gas will be 117 ml.

Can anyone please help me find molar masses of compounds. For example Copper (ll) sulfate (CuSO4)
Alina [70]

Answer:

Explanation:

You would have to add up the atomic masses of all the compounds in the compound, making sure you include how many molecules of each are in the compound

For example, in CuSOA we have 1 molecule of Cu and S, as 4 molecules of O

The atomic masses are as follows:

Cu = 63.55 u

S = 32.065 u

O = 15.99 units

This is how we would add it up:

(Atomic mass of Cu) + (Atomic mass of S) + 4(Atomic Mass of O)

(63.55) + (32.065) + 4(15.99)

(63.55) + (32.065) + 63.96

= 159.575 u

How many mole ratios can be written for a chemical reaction involving 3 substances
Anika [276]
There can be three mole ratios that can be written involving three substances.It depends on the constant of your reactant to your product. It also depends on the asked mole ratio. But the maximum would be 3 mole ratios because you have 3 substances in your reaction.
