So, here you have to look at the periodic table and see what the molar mass of each molecule composing the water compound
its two hydrogen atom plus an oxygen molecule, making it about 18g per mol.
That said, looking at the mass, we have to ask ourselves, if a mol of water contains 18g of mass, how many moles do we have in 0.5g of water?
We just do a cross multiplication:
Answer:
625: 1296
Step-by-step explanation:
625: 1296 cannot be further simplified because they share no common factor. The decimal form around 0.5822531
No, because 3 8/35 is already written in simplest form
<span>a. The number of cantaloupes sold at Central varied less than did the number sold at North.
</span>What is the MAD of the data set?
<span>{10, 9, 16, 5, 10}
</span>
mean = (10 + 9 + 16 + 5 + 10)/5 = 10
MAD = ( (10 - 10) + (10 - 9) + (16 - 10) + (10 - 5) + (10 - 10) )/5 = 12/5
The numbers of cubs in each litter were 1, 1, 2, 2, 3, 3, 3, 4, 5, and 6. The mean of these measurements is 3.
What is the mean absolute deviation?
mad = ( (3 - 1) + (3 - 1) + (3 - 2) + (3 - 2) + (4 - 3) + (5 - 3) + (6 - 3) )/10
a. 1.2
Tamar surveyed six friends, asking each how many times he or she had ridden in a helicopter. The numbers of times she recorded were 0, 0, 0, 1, 3, and 8.
What is the mean absolute deviation of the number of times? Round to the nearest tenth, if needed.
mean = (1+3+8)/6 = 2
mad = ( 2 + 2 + 2 + (2 - 1) + (3 - 2) + (8 - 2) )/6 = 14/6
c. 2.3 times
Four friends played cards. Their final scores were –6, –3, 0, and 1.
<span>What is the mean absolute deviation of their scores?
</span>
mean = (-6 - 3 - 1)/4= -10/4 = -2.5
mad = ( (6 - 2.5) + (3 - 2-5) + 2.5 + (2.5 + 1) )/2.5
mad = 4
