Answer:
n = 3.3167 moles
Step-by-step explanation:
The number of mole in water
H2O
n = m/Mm
n = number of mole
m = number of mass
Mm = number of molar mass
Given :
Mass = 59.75g
Mm of H2O
H - 1.00784
O - 15.999
Mm
H = 2 * 1.00784 = 2.01568
O = 15.999
Mm of H2O = 15.999 + 2.01568
= 18.01468
insert the values into the formula
n = m/Mm
n = 59.75/18.01468
= 3.3167moles
7,800 in expanded form would be 7,000 + 800.
Hope this helps!
Answer:
DEF = 14.5
DEG = 8.5
Step-by-step explanation:
(7x+4) + (5x+1) = 23
12x+5 = 23
x= 1.5
DEF = 14.5
DEG = 8.5
Answer:
(5,6)
Step-by-step explanation:
Add both "x" coordinates, divide by 2.
Add both "y" coordinates, divide by 2.
(2,3)
(8,9)
10 divided by 2=5
12 divided by 2 is 6
please mark me the brainiest i hope this has helped
