1 mole = 24dm^3, which is 24,000cm^3

The problem states 50 cm^3, so we need to use the 24,000 cm^3 number.

Volume of gas at room temperature = number of moles x 24,000 cm^3

50 cm^3 = number of moles x 24,000 cm^3

Number of moles = 50 cm^3 / 24,000 cm^3

Number of moles = 0.00208333 (round answer as needed)

Please help me with this question.

The answer is 4,000 ft squared because since the sides are 100 ft and 80ft then we need to multiply them which is 8,000 then divide that by 2 since it’s a triangle which is 4,000 ft squared.

A bag contains 4 marbles,6 green marbles, and 2 red. you select one ball by random. What is P red?
Komok [63]

p(outcome) = (number of desired outcomes)/(total number of outcomes)

The total number of outcomes is the sum of the numbers of the marbles.

4 + 6 + 2 = 12

The desired outcome is selecting a red ball. There are 2 red balls, so the number of desired outcomes is 2.

p(red) = 2/12 = 1/6
