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

explanation:

crosscutting concepts have application across all domains of science. as such, they are a way of linking the different domains of science. they include patterns; cause and effect; scale, proportion, and quantity; systems and system models; energy and matter; structure and function; and stability and change.

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year
