Hey there!
Mass of NaCl = 4.78 g
Molar mass of NaCl = 58.44 g/mol
Volume of solution = 12.34 mL
Number of moles:
n = mass of solute / molar mass
n = 4.78 / 58.44
n = 0.08179 moles of NaCl
Volume in liters:
12.34 mL / 1000 => 0.01234 L
Therefore:
Molarity = number of moles / Volume ( L )
Molarity = 0.08179 / 0.01234
Molarity = 6.62 M
Hope that thelps!
The answer should be compound
At 55g of Glucose/ 1000ml
1g of Glucose =(1000/55)ml
and 13g of Glucose will be 13*1000/55= 236.4ml
The patient should be given 236.4ml of the solution.
