given pressure = 1 atm temperature = 298 k

PM=DRT

where p is pressure M is molecular mass D is density R is gas constant and T is temperature

substituting the values in the equation

1\times 32=D\times 0.0821\times 298

D = 1.307 g/l.

_Al(NO3)3 +_(NH4)3 P04_AlPO4+_ NH, NO3<br>balancing equations​
astra-53 [7]

Answer:

Al(NO₃)₃ + (NH₄)₃PO₄ —> AlPO₄ + 3NH₄NO₃

The coefficients are: 1, 1, 1, 3

Explanation:

__Al(NO₃)₃ + __(NH₄)₃PO₄ —> __AlPO₄ + __NH₄NO₃

The above equation can be balance as illustrated below:

Al(NO₃)₃ + (NH₄)₃PO₄ —> AlPO₄ + NH₄NO₃

There are 12 atoms of H on the left side and 4 atoms on the right side. It can be balance by writing 3 before NH₄NO₃ as shown below:

Al(NO₃)₃ + (NH₄)₃PO₄ —> AlPO₄ + 3NH₄NO₃

Now the equation is balanced.

The coefficients are: 1, 1, 1, 3
