PLZ ANSWER FAST

Answer 1

Answer:

Explanation: we know number of moles =given wt/molecular after

For co=0.2/28=0.0072

For NH3= 0.2/16=0.0125

For Hcl=0.2 /36.5=0.0054

For h2o=0.2/18=0.0111

Order is 0.0072, 0.0054, 0.0111,0.0125

Answer 2

The increasing order is $H_{2} O$ < $NH_{3}$ < CO < HCl.

Mole:

It is defined as 6.02214076 × $10^{23}$ atoms, molecules, ions or any other chemical unit. Mole is efficient unit to make use of because of much number of atoms, molecules or any different material.

Formula to be used:

Mass = Number of moles × Molecular weight

0.2 moles of CO Carbon Monoxide = 0.2 × 28 = 5.6g

0.2 moles of $NH_{3}$  Ammonia = 0.2 × 17 = 3.4g

0.2 moles of HCl Hydrochloric Acid = 0.2 × 36 = 7.2g

0.2 moles of $H_{2} O$ Water = 0.2 × 18 = 3.6g

Since, we have quantities of all Molecules we can get the increasing order .

Therefore, the increasing order is $H_{2} O$ < $NH_{3}$ < CO < HCl.
