The formula is
m=n*M(m mass in gram,n moles,M molar mass)
M=2ArH+ArO=2+16=18g/moles
m=3.96moles*18g/moles=71.28g
hope it helps

The main purpose of following the course of a reaction by TLC is to: Group of answer choices Determine if all the starting mater
kakasveta [241]

Determine if all the starting material is converted to the product.

<h3>What is TLC?</h3>

Because it can provide immediate and important information about a sample's purity and whether or not a reaction is still ongoing, TLC is a common technique in the organic chemistry lab. A TLC plate can be finished in less than 5 minutes when low polarity solvents are used.

<h3>Uses of TLC:-</h3>

TLC is a chromatographic method used to separate mixtures that are not volatile.

Thin-layer chromatography can be used to:-

  • Assess a substance's purity.
  • Identify the compounds present in a particular combination.
  • Track the development of a reaction.

Consider the reaction cacn2 + 3 h2o → caco3 + 2 nh3 . how much caco3 is produced if 47.5 moles nh3 are produced? 1. 0.950 g 2. 9
zhannawk [14.2K]
The  CaCO3  produced  if  47.5   moles of  NH3  produced  is   calculated  as  follows

CaCN2  +3H2O  = CaCO3  + 2NH3

by  use   of  mole  ratio  between  CaCO3 to NH3  which  is 1:2  the  moles  of  CaCO3  is therefore =  47.5 /2= 23.75  moles

mass of CaCO3   is  therefore = moles  x  molar  mass
= 23.75 moles  x  100g/mol=  2375 grams   which  is approximate   2380  grams(answer 6)
