The balanced chemical equation for reaction of 
and 
is as follows:
From the balanced chemical equation, 2 mol of reacts with 1 mol of 
.
First calculating number of moles of as follows:
On rearranging,
Here, M is molarity and V is volume. The molarity of is given 0.274 M or mol/L and volume 155 mL, putting the values,
Since, 1 mol of reacts with 2 mol of thus, number of moles of will be 
.
Now, molarity of is given 0.305 M or mol/L thus, volume can be calculated as follows:
Therefore, volume of is 278.5 mL.
The average atomic mass: 40.078 u
electron configuration is the long list underneath the name "calcium" on the element. it starts with 1s^2s^2
Answer:
In this conditions, the gaswll weight 46.74 g.
Explanation:
The idal gas law states that:
PV = nRT,
P: pressure = 740 mmHg = 0.97 atm
V: volume = 14.5 L
n: number of moles
R: gas constant =0.08205 L.atm/mol.K
T: temperature = 29°C = 302.15K
1 mol gas ___ 82 g
0.57 mol gas __ x
x = 46.74 g
