Final answer:
To convert from grams of glucose to grams of NaCl, we need to calculate the number of moles of glucose and then use the molar ratio between glucose and NaCl to find the corresponding grams of NaCl.
Step-by-step explanation:
To determine how many grams of NaCl are equivalent to 90 g of glucose, we need to calculate the number of moles of glucose and then use the molar ratio between glucose and NaCl to find the corresponding grams of NaCl.
First, we calculate the number of moles of glucose using its molar mass:
Number of moles of glucose = mass of glucose / molar mass of glucose
Number of moles of glucose = 90 g / 180 g/mol = 0.5 mol
Next, we use the molar ratio between glucose and NaCl to find the corresponding grams of NaCl:
Number of grams of NaCl = number of moles of glucose x molar ratio
The molar ratio between glucose and NaCl is 1:1, so the number of grams of NaCl is also 0.5 mol.
Therefore, 90 g of glucose is equivalent to 0.5 mol or 0.5 grams of NaCl.
