Answer:
identical conditions, separate samples of O2 and an unknown gas were allowed to effuse through identical membranes simultaneously. After a certain amount of time, it was found that 6.23 mL of O2 had passed through the membrane, but only 3.85 mL of of the unknown gas had passed through. What is the molar mass of the unknown gas

Explanation:
Carbon exists in several isotopes. ... Carbon has the atomic number of 6 which means that all isotopes have the same proton number. However, the number of neutrons is different, thus giving different mass numbers. Carbon-12 has 6 neutrons, carbon-13 has 7 neutrons, and carbon-14 contains 8 neutrons.
Answer:
Did not understand your question
Explanation:
All I know is that:
Control variable is what you keep the same throughout all of the tests.
Dependant variable is what you observe from the test
Independent variable is what you are altering in the test

2 Na + Cl2 ==> NaCl
The equation of reaction needs 1 Na atom and 1 Cl atom for reactant to create 1 NaCl. You need to determine which reactant will be used up.
Natrium molecular weight is 23g/mol so the natrium you have is: 23g/ (23g/mol)= 1 mol.
Chlorine molecular weight is 35.5g/mol, so the chlorine you have is: 71g/ (35.5g/mol)= 2 mol.
The reaction will use 1 mol of natrium and 1 mol of chlorine to produce 1 mol of NaCl. The weight would be: 23g + 35.5g= 58.5 grams
