2 or 2.4 because 3 quarts is 12 cups. Now if you want to make while servings you can make 2 whole servings. But for the usage of all cups you would make 2.4 servings
12/3=2.4
1/5(100x - 105y + 70) = 20x -21y + 14
Answer:
- 0.71963 g of Zn
- 0.80256 g of HCl
Step-by-step explanation:
The required mass of reactants can be computed from the number of moles of product.
moles of ZnCl₂ = (1.5 g)/(136.282 g) ≈ 0.0110066 moles
Then the mass of Zn required is ...
mass of Zn = (0.0110066 mol)(65.382 g/mol) = 0.71963 g
Two moles of HCl are used in the reaction with each mole of Zn, so the mass of HCl required is ...
mass of HCl = 2(0.0110066 mol)(36.458 g/mol) = 0.80256 g
_____
<em>Comment</em>
The discrepancy in the last two decimal places of the weights above versus the calculator output below comes from rounding of moles of Zn to 4 significant digits, instead of 5 or more. The number of moles of ZnCl₂ is closer to 0.0110066.
Answer:
The line passing through the given points is:

in its slope-intercept form
Step-by-step explanation:
Start by finding the slope of the segment that joins the two given points using the slope formula:

which for our case renders:

Now we can find the y-intercept by using any one of the given points in the general slope-intercept form of a line with this slope:

Therefore, the equation of the line becomes:
