Answer:
.055 mol/L
Explanation:
Henry's Law is about solubility of a gas in a liquid which is dependent on the partial pressure of gas above the liquid . According to it
C = k P where C is concentration of gas in the liquid , k is henry's constant and P is partial pressure of the gas .
Given k = .159 mol/L.atm
P = 265 mm of Hg
= 265 / 760
= .34868 atm
C = kP
= .159 x .34868
= .055 mol/L
Answer:
Ba^2+ (aq) +SO4^2- (aq) →BaSO4(s)
Explanation:
you really need to learn how to do this yourself - its really important throughout level chem, pre-ap chem, and especially if you plan on moving on to ap chem!!
Answer:
AINO3 - 89 g/mol
Explanation:
Molar mass of a compound or molecule is obtained by summing the individual atomic masses of the elements that makes the compound.
In this question, the elements are Al, N and O
The molar mass is given as;
Molar mass = Al + N + 3 (O)
Al = 27
N = 14
O = 16
Molar mass = 27 + 14 + 3(16)
Molar mass = 89 g/mol
