2. if 93.5 cm of mg ribbon has mass 1.473 g, calculate the length of ribbon you must cut to get 0.0535 g of mg. (hint: this is just a proportion.)
Answer
Explanation:
Step1: Set up proportion
Let ( x ) be the length of ribbon. Proportion: (\frac{93.5}{1.473}=\frac{x}{0.0535})
Step2: Solve for ( x )
Cross - multiply: (x=\frac{93.5\times0.0535}{1.473}) Calculate numerator: (93.5\times0.0535 = 5.00225) Then (x=\frac{5.00225}{1.473}\approx3.4)
Answer:
(3.4) cm
