( (0.1095 mmol/mL)(25 mL) - (0.1482 mmol/mL)(29.04 mL) ) / ( (1000 mg/g)(1.3010 g) )
what is the answer
i got -.0012 but its wrong
To accurately calculate the answer to the given expression, we need to follow the given calculations step by step.
Let's break down the expression:
( (0.1095 mmol/mL)(25 mL) - (0.1482 mmol/mL)(29.04 mL) ) / ( (1000 mg/g)(1.3010 g) )
Step 1: Perform the multiplication within each set of parentheses.
For the first set of parentheses:
0.1095 mmol/mL * 25 mL = 2.7375 mmol
For the second set of parentheses:
0.1482 mmol/mL * 29.04 mL = 4.3080288 mmol
After this simplification, the expression becomes:
(2.7375 mmol - 4.3080288 mmol) / ( (1000 mg/g)(1.3010 g) )
Step 2: Perform the subtraction in the numerator.
2.7375 mmol - 4.3080288 mmol = -1.5705288 mmol
Now the expression becomes:
(-1.5705288 mmol) / ( (1000 mg/g)(1.3010 g) )
Step 3: Perform the multiplication in the denominator.
(1000 mg/g)(1.3010 g) = 1301 mg
Now the expression becomes:
(-1.5705288 mmol) / 1301 mg
Step 4: Convert mg to mmol for consistency in units.
Since 1 mmol equals 1000 mg, we can divide by 1000 to convert mg to mmol:
1301 mg / 1000 = 1.301 mmol
Now the expression becomes:
(-1.5705288 mmol) / 1.301 mmol
Step 5: Perform the division.
(-1.5705288 mmol) / 1.301 mmol = -1.2076
So the answer to the given expression is -1.2076.
It seems you made an error in one of the intermediate steps of the calculations. By following these steps correctly, you can verify and obtain the accurate result.
