Answer:

8

Explanation:

From the question given above, the following data were obtained:

Empirical formula = C₅H₇

Molecular weight = 537 amu.

Number of empirical unit (n) =?

We can obtain the number of empirical units in the actual molecular formula by doing the following:

[C₅H₇]n = 537

[(12×5) + (1×7)]n = 537

[60 + 7]n = 537

67n = 537

Divide both side by 67

n = 537/67

n = 8

Thus, there are 8 empirical units in the molecular formula

True. Each contour line on a topographic map represent a certain elevation; the closer they are, the steeper the surface is. All points on a contour line are the same elevation.

An animals life in a desert is to survive, depending on the type of desert though, but I assume the most common desert, the hot/dry desert. Most animals are nocturnal, because it becomes cooler at night, and live underground during the day.

Calculate moles of oxygen atoms in 0.68mol of KMnO4
Dominik [7]
Alright, so that means we have 0.68 mol of the compound


For each 1 mol of the compound, we have 4*1 oxygens (because there are four oxygens in the formula)
Therefore for each 0.68 mol of the compound, we have 4*0.68 moles of oxygen!
