Explanation:
Answer:
6,1,2
Explanation:
_Ag + _N2 => _Ag3N
LHS RHS
Ag=1×6=3 Ag=3×2=6(Balanced)
N=2×1=2 N=1×2=2(Balanced)
coefficient=6,1,2
Hey there!
<span>Use the equation of Clapeyron:
</span>
T in kelvin :
26 + 273.15 => 299.15 K
R = 0.082
V = 10.2 L
P = 0.98 atm
number of moles :
P *V = n * R * T
0.98 * 10.2 = n * 0.082 * 299.15
9.996 = n * 24.5303
n = 9.996 / 24.5303
n = 0.4074 moles
Therefore:
Molar mass H2O = 18.01 g/mol
1 mole H2O ------------- 18.01 g
0.4074 moles ----------- m
m = 0.4074 * 18.01 / 1
m = 7.339 g of H2O
Answer: 325 mg
Explanation:
Grains ---> ounces -----> pounds -----> grams -----> mg
5 gr x (0.00229 oz / 1 gr) x (1 lb / 16 oz) x (454 g / 1 lb) x (1000 mg / 1 g) = 325 mg
