Solid sodium reacts violently with water, producing heat, hydrogen gas, and sodium hydroxide. how many molecules of hydrogen gas are formed when 48.7 g of sodium are added to water? show your work. (4 points) 2na + 2h2o > 2naoh + h2 2na + 2h2o > 2naoh + h2 48.7 g ? molecules 2 mol na= 1 mol h2 1 mol na= 23g na 1 mol h2= 6.02x1023 molecules (48.7g na/1)x(1 mol na/23g na)x(1 mol h2/2mol na)x(6.02x1023/1 mol h2) (48.7)(6.02x1023)/(23)(2)= 293.174x1023 molecules can someone tell me what i did wrong?

Number of molecules of hydrogen gas

Explanation:

Number of moles of sodium =

According to reaction , 2 moles of sodium produces 1 mole of hydrogen gas , then 2.11 mol of sodium will= of hydrogen gas that is 1.05 moles of hydrogen gas.

Number of molecules = moles of substance

Moles of hydrogen gas formed = 1.05 moles

Number of molecules of hydrogen gas = moles of hydrogen gas

Number of molecules of hydrogen gas

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
