Answer:

666.95 $

Explanation:

If In a scale drawing of a dining room floor plan 10 mm = 2 meters

then 40 mm = (40 × 2) / 10 = 8 meters

and 32 mm = (32 × 2) / 10 = 6.4 meters

area of the dining room = 8 × 6.4 = 51.2 m²

1 square yard = 0.836 squared meters (m²) and it costs 10.89 $

Now we devise the following reasoning:

if        0.836 m² of flooring costs 10.89 $

then       51.2 m² of flooring costs X $

X = (51.2 × 10.89) / 0.836 = 666.95 $

What is the molarity of NO−3 in 0.160M KNO3?
zubka84 [21]
A solution of KNO3 consists of ions of potassium and nitrate. The ionic equation is expressed as:

KNO3 = K+ + NO3-

There is 1 is to 1 ratio between the substances. So, the molarity of NO3- in the solution is calculated as follows:

0.160 mol / L KNO3 ( 1 mol NO3- / 1 mol KNO3 ) = 0.160 M NO3-
