Idk i’m on that question now
You have to use the molar volume of gas which is 22.4L/mol at STP. To find the number of moles of from a given volume of gas at STP, you need to divide the given volume by 22.4L/mol.
44.4L/22.4L/mol=1.98mol of gas
A binary compound is a compound formed from two different elements. There may or may not be more than one of each element. A diatomic compound (or diatomic molecule) contains two atoms, which may or may not be the same.

PH value of 0.10 m of HBr, a strong acid.
When dissolved in water it gives H+ and Br-, so H+ is the concentration.
pH = - log H+) => pH = - log (0.10) = -(-1) = 1
HF and HC2H3O2 are weak acids. They both will have pH value greater than 1 as they ionize in solution.
Answer:
308,4796 g.
Explanation:
1 mol equals to 107,86 g, now times 2,86 mol, 308,4796 g.
