Milk that’s really sweet? or clumpy milk?
If 1000 ml (1 L) of CH₃COOH contain 1.25 mol
let 250 ml of CH₃COOH contain x
⇒ x =
= 0.3125 mol
∴ moles of CH₃COOH in 250ml is 0.3125 mol
Now, Mass = mole × molar mass
= 0.3125 mol × [(12 × 2)+(16 × 2)+(1 × 4)] g/mol
= 18.75 g
∴ Mass of CH₃COOH present in a 250 mL cup of 1.25 mol/L solution of vinegar is <span>18.75 g</span>
Answer:
Attached is the solution to the question
Explanation:
The answers are as follows:
1. TRUE, <span>The energy in a nuclear reaction comes from the transformation of mass to energy.
</span>
2. TRUE, <span>Although both fission and fusion generate energy, fusion produces much more energy than nuclear fission and produces less nuclear waste
</span>
3. TRUE, <span>In certain types of atomic bombs, a fuel, like plutonium-239, is bombarded with neutrons to create an uncontrolled nuclear reaction that splits the nuclei of the fuel.
