A 1 molar solution is the molecular weight in grams in 1 litre of water, so a 3.5 molar solution would be 58.44g multiplied by 3.5, which is 204.54g in 1L
There was a change in its color from white to red which can only be changed by a chemical reaction
Use Ideal gas law to solve. PV=mRT you have pressure (1.02atm), temperature (295K or 22°C), mass of KClO3(11.83g) , and universal gas constant on a molar mass basis (R=R_bar/M). Just make sure you units are consistent and use the ideal gas equation to solve for Volume. M, should be the total Molar mass for KClO3.
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
