A "carat" is a unit of mass defined as exactly ⅕ of a gram. There are exactly 5 carats in a gram. How many carats would a 1.0 mL

lana66690 [7]

Answer:

17.55 carats

Explanation:

First, there is a need to know the mass of 1.0 mL of diamonds. The density of diamond is 3.51 g/mL and density is the ratio of mass and that of volume. Hence;

mass of diamond = density of diamond x volume.

Since the volume of the diamond is 1.0 mL and the density is 3.51 g/mL,

mass of 1.0 mL of diamond = 3.51 x 1.0 = 3.51 g.

1 g = 5 carats, therefore 3.51 g would be;

3.51 x 5 = 17.55 carats.

Hence, there would be 17.55 carats of diamond in 1.0 mL of diamond.

Given the following reaction: 3D(g) + E(g) + 2F(g) → 5G(g) + 4H(g)

evablogger [386]

Answer:

Explanation:

Hello,

The law of mass action, allows us to know the required amounts, thus, for this chemical reaction it is:

$\frac{1}{-3} \frac{d[D]}{dt} =\frac{1}{-1} \frac{d[E]}{dt} =\frac{1}{-2} \frac{d[F]}{dt} =\frac{1}{5} \frac{d[G]}{dt} =\frac{1}{4} \frac{d[H]}{dt}$

Now, we answer:

(a)

$\frac{d[H]}{dt}=4*\frac{1}{-3} *(-0.12M/s)=0.16M/s$

(b)

$\frac{d[E]}{dt}=-1*\frac{1}{5} *(0.2M/s)=-0.04M/s$

(c) Since no initial data is specified, we could establish the rate of the reaction as based of the law of mass action:

$r=\frac{1}{-3} \frac{d[D]}{dt} =\frac{1}{-1} \frac{d[E]}{dt} =\frac{1}{-2} \frac{d[F]}{dt} =\frac{1}{5} \frac{d[G]}{dt} =\frac{1}{4} \frac{d[H]}{dt}$

Thus, any of the available expressions are suitable to quantify the rate of the reaction.

Best regards.
