Answer:
7 μl /s
Explanation:
Given data:
0.44 mL/min
μl /s = ?
Solution:
First of all we will convert the mL/min to mL/s.
we will divide the given value by 60.
0.44/60
0.007 mL/s
Now we will convert the mL/s to μl /s.
we will multiply the value with 1000.
0.007 × 1000
7 μl /s

First, calculate the molar mass of Na2CO3 by looking up the molar mass of the elements used in it.
Sodium = 22.989769
Carbon = 12.0107
Oxygen = 15.999
Multiply each molar mass by the number of atoms used, and sum the results to get the molar mass
2 * 22.989769 + 12.0107 + 3 * 15.999 =105.9872
Finally, multiply the molar mass by the number of moles you need.
0.752 * 105.9872 = 79.7024 grams</span>
