A chemist has a 12.5 liter sample of neon gas at 1.00 atm and 30 c. If the chemist compresses the sample to 10.5 liters and hold
ycow [4]

Answer:

254.5 K

Explanation:

Data Given

initial volume V1 of neon gas = 12.5 L

final Volume V2 of neon gas = 10.5 L

initial Temperature T1 of neon gas = 30 °C

convert Temperature to Kelvin

T1 = °C +273

T1 = 30°C + 273 = 303 K

final Temperature T2 of neon gas = ?

Solution:

This problem will be solved by using Charles' law equation at constant pressure.

The formula used

                        V1 / T1 = V2 / T2

As we have to find out Temperature, so rearrange the above equation

                       T2 = V2 x T1 / V1

Put value from the data given

T2 = 10.5 L x 303 K / 12.5 L

T2 = 254.5K

So the final Temperature of neon gas = 254.5 K

Paper clips are made of stainless steel. Steel is a mixture. There are different kinds of steel that have slightly different rat
77julia77 [94]

No, firstly bc stainless steel and carbon steel mixed with different things, high-density metals and carbon.

High-density metals and carbon both has different density which will affect the steel when they combined with iron. So it cant be the same.

What is the molarity of a solution that contains 4.87 g KCI (74.55 g/mol) dissolved in in 500.0 ml water?
lbvjy [14]

Answer:

Molarity = 0.13M

Explanation:

n=m/M = 4.87/74.55= 0.065mol, V= 500ml= 0.5dm3

Applying

n= C×V

0.065= C×0.5

C= 0.13M
