V1/T1 = V2/T2
V1= 3.5 L
T1 = 25 +273=298 K
T2 = 40.9 + 273 = 313.9 K
V2- ?
3.5 L/298 K= V2/ 313.9 K
V2 = (3.5 L*313.9 K)/298 K ≈ 3.69 L
Answer:
answer will be b
Explanation:
mole is given 0.20
you have to find mass so just convert it into mass
remember if you move away from mole you multiply and if you move towards mole you divide so
just multiply mole with molar mass of glucose
so
0.20×180 = 36 grams
simple keep learning.......
its definitely not photosynthesis!
its probably metamorphosis but i could be wrong
99.6 mg= .0996 g
.0996g x (1mol/125.05g) x (1 mol SO3/1 mol Na2SO2) x (6.02 x 10^22/1mol SO3) = 4.79 x 10^19 SO32- ions
