Which of these values for the number of feet in a mile is most accurate, when compared to the exact value?
A. 5,200
B. 5,290
C. 5,000
D. 5,300

B. 5,290 feet

Step-by-step explanation:

1 Mile =  5280 Feet

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
