Just did this question on Mastering Chem, it's 1
Hello there!
First you had to multiply by the density by the volume since D=M/V. Please make sure when your units has the same thing and it should be cancel it out.
2.3g/mL*30 mL= 69L is the right answer.
Hope this helps!
Thank you for posting your question at hereon Brainly.

Answer:
See image attached
Explanation:
a)
The full reaction mechanism of step 1 was obtained from Bartleby and attached to this answer. The steps involved in the reaction are:
1) Loss of Br- and formation of a carbocation
2) Attack of CH3CN on the carbocation
4) Formation of a quaternary nitrogen intermediate
5) Attack of water on the quaternary nitrogen intermediate
6) Loss of the water molecule
5) Formation of the amide product
b)
i) sodium hydroxide
ii) HCl
Answer:
The thermic effect of food.
Explanation:
The process in which metabolic rate increase after meal is called the THERMIC EFFECT OF FOOD.
THERMICAL EFFECT OF FOOD can be defined as the way in which some calories a person or an individual consumed after meal help to break down the food for easy absorbing and to store the food consumed while some are burn off during execise which is why a person or an individual metabolic rate may elevate after meal, during exercise or due to some other factors reason been that human body makes use of energy everyday due to day to day activities.
Example a person who consumed a protein food may experience high THERMIC EFFECT than the person who consumed food that contained fat or carbohydrates reason been it can take a long time for such person body to break down the food, burn and absorb the protein.
Therefore The increase in metabolic rate after a meal is called THERMIC EFFECT OF FOOD.
Answer;
1.6 kg.
Solution;
The density is 1.36 g/ml;
The volume is 1.25 qt
However; 1 qt = 946.35 ml
Mass is given by; density × volume;
= 1.25 qts × 946.25 ml/qt × 1.36 g/ml =1609 g
but; 1 kg = 1000 g
Hence the mass = 1609/1000 = 1.609 Kg or 1.61 (sig figs)
