For us to accurately determine what compound
this is, additional info must be given. However I can suggest two compounds
which have molecular mass of about 30.07 g/mol.
1. It could be NO or nitric oxide.
The molecular mass is 16 + 14= 30 g/mol
But if we search the exact weight, it is 30.01 g/mol
2. It could also be (CH3)2 or ethane.
The molecular mass is 2*12+ 6*1= 30 g/mol
But if we search the exact weight, it
is 30.07 g/mol.
<span>So we could say it more likely to to be (CH3)2 </span>
C. 1.0 M Al2O3 would be the best answer
Answer:
113.8g
Explanation:
Statement of problem: mass of 1.946mole of NaCl
Given parameters:
Number of moles of NaCl = 1.946mole
Unknown: mass of NaCl
Solution
To find the mass of NaCl, we apply the concept of moles which expresses the relationship between number of moles and mass according to the equation below:
Number of moles = 
To find the molar mass of NaCl:
the atomic mass of Na = 23g
atomic mass of Cl = 35.5g
Molar mass of NaCl = (23 + 35.5) = 58.5gmol⁻¹
Mass of NaCl = Number of moles x molar mass of NaCl
Mass of NaCl = 1.946 x 58.5 = 113.8g
