( (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.
