Answer:
49.14 carat.
Explanation:
From the question given above, we obtained the following data:
Volume of diamond = 2.8 mL
Mass of diamond (in carat) =.?
Next, we shall determine the mass of diamond in grams (g). This can be obtained as follow:
Volume of diamond = 2.8 mL
Density of diamond = 3.51 g/mL
Mass of diamond ( in grams) =?
Density = mass /volume
3.51 = mass /2.8
Cross multiply
Mass of diamond (in g) = 3.51 × 2.8
Mass of diamond (in g) = 9.828 g
Finally, we shall Convert 9.828 g to carat. This can be obtained as follow:
1 g = 5 carat
Therefore,
9.828 g = 9.828 g /1 g × 5 carat
9.828 g = 49.14 carat.
Therefore, the mass of the diamond in carat is 49.14 carat.
Answer:
Product: propan-1-ol
Explanation:
IIn this case, we have to remember that 
is a reduction agent. So, this is a <u>reduction reaction</u>. The has the ability to produce <u>hydride ions </u>
. This ion can attack the <u>carbonyl group</u> generating a negative charge in the oxygen. In the next step, the negative charge in the oxygen can attack a water molecule to<u> protonate</u> the molecule and produce <u>propan-1-ol</u>.
