Answer:
15 g/mol
Explanation:
If you need to round 14.8232 g/mol down to 2 significant figures, you start on the left, count in two (14) and round with the next number (.8).
Because 8 is higher than 4, you round up, getting the answer 15.
Answer:
Nonpoint-source-pollution
Explanation:
All of the acid molecules in beaker 1 dissociate fully and exist as and ions. As a result, beaker 1 represents a strong acid solution. The majority of the molecules in beaker 2 are undissociated.
The NaOH can react with HCl with the formula: NaOH + HCl = NaCl + H2O. So if you want to neutralize the solution, the molar number of NaOH and NCl need to be equal. So we need 0.3*50/0.1=150 milliliters.
