PLEASE help due in 25 minutes Determine the mass in grams of each of the following:
5.04 x 1024 atoms N

2.01 x 1024 atoms Ca

8.32 x 1021 atoms Sn

Determine the number of particles contained in each of the following:
50.3 g Cu

145g Si

0.67 g Cl

method to do this given in explaination

Explanation:

divide the number of atoms with avagadro constant and multiply with the molar mass of each atom - to obtain the mass in g

divide the mass with molar mass and multiply with avagadro constant to obtain the number of particles

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
