Answer:
if what you need is the final answer
the final answer is = 0.228 and I think the unit is Liter(L).
Explanation:
Answer:
The density of water 
.
Explanation:
Density of water = 1.00 g/mL
1 lb = 453.592 g
Density of the water in 
:
The density of water .
Answer:
77 L of water can be made.
Explanation:
Molar mass of 
= 32 g/mol
So, 55 g of = 
mol of = 1.72 mol of
As hydrogen is present in excess amount therefore is the limiting reagent.
According to balanced equation, 1 mol of produces 2 mol of 
.
So, 1.72 mol of produce 
mol of or 3.44 mol of .
Let's assume gas behaves ideally at STP.
Then, 
, where P, V, n, R and T represents pressure, volume, no. of moles, gas constant and temperature in kelvin scale respectively.
At STP, pressure is 1 atm and T is 273 K.
Here, 
= 3.44 mol and R = 0.0821 L.atm/(mol.K)
So, 
Option (b) is correct.
The experimental procedure would provide evidence that plants need
nitrogen to grow is by
- Identical plants are placed in two air-tight containers with sufficient exposure to sunlight.
- One container has nitrogen gas, and the other has room air. The scientist measures plant growth
It is necessary to use identical plants during the experiment as plants have
different rates of nitrogen absorption from the soil. It should also be done in
air-tight containers called terrariums to prevent loss or contamination of the
gases with other elements/compounds.
The identical plants containing nitrogen and room air should both be
measured for the growth difference between them.
