1. how many atoms are there in 2.8 moles of carbon? you must show your work to receive credit.

2. how many moles are 1.50 x 10^23 molecules of naoh? must show work to receive credit.

you! : )

The answer to your question is

1.-  1.686 x 10²⁴ atoms

2.- 0.25 moles

Explanation:

1.-

              1 mol 6.023 x 10²³ atoms

             2.8 moles  x

              x = (2.8 x 6.023 x 10²³) / 1

              x = 1.686 x 10²⁴ atoms

2.-           1 mol 6.023 x 10 ²³ molecules

               x moles  1.50 x 10²³ molecules

              x = (1.50 x 10²³ x 1) / 6.023 x 10²³

              x = 0.25 moles                                                      

what is the general relationship between a galaxy's distance from earth and its speed?

the answer is:

the farther away a galaxy is from us, the faster it is moving away from us.

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
