In this particular reaction 4-methylbenzaldehyde and benzyltriphenylphosphonium chloride were reacted together in the presence of sodium hydroxide and the product with the structure shown in the answer was obtained as the major isomer produced in the reaction.
Answer:
12,000 units of heparin are received by patient in 24 hours.
Explanation:
10,000 units of heparin in 1000ml of D5W.
Units of heparin in 1 mL =
Rate at heparin drip set at = 50 ml/hour
Units of heparin in 50 ml of solution =
500 units of heparin are received by patient in an every hour.So, in 24 hours patient will receive:
of heparin
