Answer:
The answer to your question is: 16.7 g of KBr
Explanation:
Data
mass KBr = ? g
Volume = 0.400 L
Concentration = 0.350 M
Formula
Molarity = moles / volume
moles = molarity x volume
Process
moles = (0.350)(0.400)
= 0.14
MW KBr = 39 + 80 = 119 g
119 g of KBr -------------------- 1 mol
x -------------------- 0.14 mol
x = (0.14 x 119) / 1
x = 16.7 g of KBr
Answer:
0.54 L
Explanation:
Given that,
Initial volume, V₁ = 0.5 L
Initial temperature, T₁ = 10°C = 283 K
Final temperature, T₂ = 35 C = 308 K
We need to find the final volume. The relation between the volume and temperature is given by :
So, the new volume is 0.54 L.
B. He would be considered an Organic Chemist since Organic Chemistry is the study of Carbon and its compounds.
Answer: All of these I’m pretty sure
Explanation: It just makes sense
Answer:
Yes, this ring is pure gold because when we divide the mass by the volume we get our density for the ring, which comes out to about 19.32.
