Answer:
i dont know
Step-by-step explanation:
The answer is <span>A.0.5 moles
</span><span>a mole of sodium chloride weighs approximately 58 grams: 1 M - 58 g
</span><span>you have 29 grams of sodium chloride, how many moles of sodium chloride do you have: xM - 29g
1 M : 58g = x : 29 g
x = 1 M : 58g * 29 g = 0.5 M</span>
To solve, you start with distributive property and multiply 7 by n and 3 for
7n-21<-63 the you get the 7n alone by adding 21 to -63 and the 21 for 7n<-42. now you divide 7 by itself and 42 for n<-6
There would be 35 calories in each slice of pie. All you have to do is divide the total number of calories (280) by the number of slices (8) and you find out there are 35 calories in each piece
