Explanation:
When you start to feel you are desiring more than just a casual friendship with your best friend and you’re not sure what to do next, let me offer you some advice that could strengthen both your relationship and your love for each other.
First, don’t rush into a romantic relationship with your best friend…many times people confuse love with that other kind of caring love you feel for all of your other friends.
Second, don’t spill your guts right away. You might feel like you have to share all your thoughts and feelings with the other person as soon as you start to feel something. That’s usually a mistake.
Answer:
Number of moles = 10.6 mol
Explanation:
Given data:
Molar mass of H = 1.008 g/mol
Molar mass of C = 12.01 g/mol
Molar mass of O = 16.00 g/mol
Mass of citric acid = 2.03 kg (2.03×1000 = 2030 g)
Number of moles of citric acid = ?
Solution:
Formula:
Number of moles = mass/molar mass
Now we will calculate the molar mass of citric acid:
C₆H₈O₇ = (12.01× 6) + (1.008×8) + (16.00×7)
C₆H₈O₇ = 72.06 + 8.064+112
C₆H₈O₇ = 192.124g/mol
Number of moles = 2030 g/ 192.124g/mol
Number of moles = 10.6 mol
