Answer:
$200.0 is the cost for installing a carpet for a room that measures 12.0 feet by 15.0 feet.
Explanation:
Length of the room = l = 15.0 ft =
Width of the room = w = 12.0 ft =
(1 yard = 3 feet)
Area of the room = l × w =
Cost for installing a carpet for a room = $10 per square yard
Cost for installing a carpet for a room wit area 20.0 square yard :
$200.0 is the cost for installing a carpet for a room that measures 12.0 feet by 15.0 feet.
Explanation:
Mass of fructose = 33.56 g
Mass of water = 18.88 g
Total mass of the solution = Mass of fructose + Mass of water = M
M = 33.56 g + 18.88 g =52.44 g
Volume of the solution = V = 40.00 mL
Density =
a) Density of the solution:
b) Molar mass of fructose = 180.16 g/mol
Moles of fructose =
Molar mass of water = 18.02 g/mol
Moles of water=
Mole fraction of fructose in this solution:
Mole fraction of water =
c) Average molar mass of of the solution:
=
d) Mass of 1 mole of solution = 42.50 g/mol
Density of the solution = 1.311 g/mL
d) Specific molar volume of the solution:
