It should be 24.2624 because if there’s 2.72g in every cm3 and there are 8.92 cm3, then you simply multiply the two numbers
hope this helped :)
Though all the options aren't visible i think she tried to find out the force friction at different surfaces.
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>
Move the buret clamp to a ring stand with a larger base.
Answer:
The processes are condensation, precipitation, evaporation and transpiration. The rock cycle and water cycle overlap with erosion, transporting, and deposition. This is where the life cycle interacts with the rock cycle. Life decomposes and releases carbon back into the soil, which eventually becomes sedimentary rock.
