The percent by mass of water in Na2So4 10H2O is 55.9%
calculation
% mass = molar mass of water(H2O) in Na2SO4 .10H2O/ molar mass of Na2SO4. 10H2O x100
that is mass of H2O = 10{ ( 1x2) + 16} = 180 g/ mol
mass of Na2SO4.H2O= { (2 x23)+ 32 + ( 16 x4 ) + 180 = 322 g/mol
therefore the % mass composition = 180/322 x100 =55.9 %

Answer: i'm pretty sure it's b if i remember correctly.
Explanation:
i learned this a while ago so i'm not completely sure.
Answer: the formula of the hydrate is CoCl2.6H2O
Explanation:Please see attachment for explanation
According to ideal gas equation, we have
PV = nRT
According to above equation, pressure exhibited by any gas depends upon number of moles of gas, temperature and volume.
Thus, <span>pressure of a refrigerant cylinder containing saturated refrigerant is determined by temperature, number of moles of gas and volume occupied. In general, pressure exhibited by system will increase with increase in temperature and number of mole of gas, while it will decrease with increasing volume. </span>
