Hello!
Ok so for this problem we use the ideal gas law of PV=nRT and I take it that the scientist needs to store 0.400 moles of gas and not miles.
So if we have
n=0.400mol
V=0.200L
T= 23degC= 273k+23c=296k
R=ideal gas constant= 0.0821 L*atm/mol*k
So now we rearrange equation for pressure(P)
P=nRT/V
P=((0.400mol)*(0.0821 L*atm/mol*k)*(296k))/(0.200L) = 48.6 atm of pressure
Hope this helps you understand the concept and how to solve yourself in the future!! Any questions, please feel free to ask!! Thank you kindly!!!
Mg3(PO4)2 - Mg²⁺ forms base
PO4³⁻ forms acid
Ma(OH)2 is a base(Y).
H3PO4 is an acid(X).
3Mg(OH)2 + 2H3PO4 ---> Mg3(PO4)2 + 3H2O
