The solubility of Cu(NO3)2 is 6.83 grams per 100 grams of water (d=0.9982 g/ml). How many grams of Cu(NO3)2will dissolve in 175 ml of water?
6.83/100gwater= S/(175*.9982)grams
solve for S.
To calculate the number of grams of Cu(NO3)2 that will dissolve in 175 ml of water, we need to use the given solubility information.
The solubility of Cu(NO3)2 is given as 6.83 grams per 100 grams of water. However, in this case, we are given the volume of water in milliliters (ml). So, we need to convert the volume from ml to grams using the density of water.
Density is defined as mass divided by volume. In this case, the density of water is given as 0.9982 g/ml. So, to convert ml to grams, we multiply the volume (175 ml) by the density (0.9982 g/ml):
175 ml * 0.9982 g/ml = 174.635 grams
Now, we have the mass of water in grams. To calculate the amount of Cu(NO3)2 that will dissolve in this amount of water, we use the solubility given:
6.83 grams of Cu(NO3)2 dissolve in 100 grams of water.
To find the amount of Cu(NO3)2 that will dissolve in 174.635 grams of water, we can set up a proportion:
(6.83 grams / 100 grams) = (x grams / 174.635 grams)
Cross-multiplying gives us:
100 * x = 6.83 * 174.635
100x = 1189.40205
x = 11.894 grams
Therefore, approximately 11.894 grams of Cu(NO3)2 will dissolve in 175 ml of water.
