Chapter 1: Q58 E (page 66)

Write conversion factors (as ratios) for the number of:

(a) kilometers in 1 mile

(b) liters in 1 cubic foot

(c) grams in 1 ounce

Short Answer

Expert verified

(a) 1.6093 km/mile

(b) 28.317 L/\(f{t^3}\)

(c) 31.103 gm/oz

Step by step solution

01

Common conversion factor:

A unit conversion factor is a ratio of two equivalent amounts expressed in different measuring units.

02

Explanation for kilometers in 1 mile:

No. of miles in 1km = 0.62137mile so,

Conversion factor becomes

\(\frac{{1.6093km}}{{1mile}}\).

03

Explanation for liters in 1 cubic foot:

No. of liters in 1 ft3= 28.317L.

Conversion factor becomes

\(\frac{{28.317L}}{{1f{t^3}}}\)

04

explanation for grams in 1 ounce:

No. of gm in 1 oz = 31.103g.

Hence, conversion factor becomes

\(\frac{{31.103g}}{{1oz}}\)

Yeast converts glucose to ethanol and carbon dioxide during anaerobic fermentation as depicted in the simple chemical equation here:

\({\rm{Glucose}} \to {\rm{Ethanol + Carbon Dioxide}}\)

(a) If\(200.0g\)of glucose is fully converted, what will be the total mass of ethanol and carbon dioxide produced?

(b) If the fermentation is carried out in an open container, would you expect the mass of the container and contents after fermentation to be less than, greater than, or the same as the mass of the container and contents before fermentation? Explain.

(c) If\(99.7g\)of carbon dioxide is produced, what mass of ethanol is produced?

Question: The mercury content of a stream was believed to be above the minimum considered safe – 1 part per billion (ppb) by weight. An analysis indicated that the concentration was 0.68 parts per billion. What quantity of mercury in grams was present in 15.0 L of the water, the density of which is 0.998 g/ml? \(\left( {1ppbHg = \frac{{1ngHg}}{{1gwater}}} \right)\)

The density (d) of a substance is an intensive property that is defined as the ratio of its mass(m) to its volume (V).

\(\begin{aligned}{\rm{density = }}\frac{{{\rm{mass}}}}{{{\rm{volume}}}}\\{\rm{d = }}\frac{{\rm{m}}}{{\rm{v}}}\end{aligned}\)

Considering that mass and volume are intensive properties, explain why their ratio, density is intensive.

Question: A chemist’s 50-Trillion Angstrom Run (see Exercise 1.78) would be an archeologist’s 10,900 cubit run. Howlong is one cubit in meters and in feet? (1 Å = 1 × 10-8 cm)

When elemental iron corrodes it combines with oxygen in the air to ultimately form red brown iron(III) oxide which we call rust.

(a) If a shiny iron nail with an initial mass of 23.2 g is weighed after being coated in a layer of rust, would you expect the mass to have increased, decreased, or remained the same? Explain.

(b) If the mass of the iron nail increases to 24.1 g, what mass of oxygen combined with the iron?
