Answer:
3.44 liters
Explanation:
before we start we must convert the celcius to kelvin by adding 273
Next we must Know we are using charles law and the eqation is V1/T1= V2/T2 we must convert it to V1 T1 / T2
so its must equal 7.80 times 698 divided by 308 wich gives you 3.44 liters
Answer:
Molarity of solution is 0.0928 M.
Explanation:
Balanced equation:
Number of moles of in 10.8 mL of 0.0215 M solution
= = 0.000232 moles
Let's assume molarity of solution is S(M)
Number of moles of in 12.50 mL of S(M) solution
= = 0.0125S moles
According to balanced equation, 5 moles of react with 1 mol of
So, 0.0125S moles of react with moles of
Hence,
or, S = 0.0928
So, molarity of solution is 0.0928 M.
Answer:
D
Explanation:
because they need it and hii
C10H8N2O2S2
C=12,H=1,N=14,O=16,S=32
R. F. M (Relative Formula Mass)=(12*10)+8+(2*14)+(2*16)+(2*32)
Number of moles =given mass/formula mass
=29/252
=0.1151 moles
