galina1969 [7]

Answer:

please mark my answer brainliest

Explanation:

nice question...

ok solution goes right the way through...

in temp 193°C the volume of gas was 892ml

so for...144°C the volume of gas will be 892/193x144=665.533 or 665.534...(rounded off)...or 665°...(approx)....so got ur answer...

I hope it helps....

please comment if you have any further questions...i will be solving it for u...

Diamonds are measured in carats, and 1 carat=0.200 g. The density of diamond is 3.51 g/cm^3. What is the volume of a 5.0 - carat

Blizzard [7]

Answer:- Volume of the 5.0 carat diamond is $0.28cm^3$ .

Solution:- It is a unit conversion problem. Need to convert carat to grams and then using grams and density the volume could easily be calculated.

We have 5.0 carat diamond and asked to calculate it's volume. Density of diamond is given as $3.51\frac{g}{cm^3}$ and 1 carat = 0.200 g. Let's do this step by step:

First step is the conversion of carat to grams:

$5.0carat(\frac{0.200g}{1carat})$ = 1.0 g

In second step, grams are converted to volume using the given density as:

$volume=\frac{mass}{density}$

$volume=1.0g(\frac{1cm^3}{3.51g})$

$volume=0.28cm^3$

So, the volume of the 5.0 carat diamond is $0.28cm^3$ .
