Answer:
300 kg
Explanation:
The give parameters obtained from a similar question are;
The mass of oseltamivir per capsule = 75 mg
The mass of oseltamivir required, <em>M</em>, is given as follows;
M = The mass of oseltamivir per capsule × The mass taken per person per day × 5 days × The number of people in the city
M = 0.75 mg/capsule × 2 capsule/(day·person) × 5 days × 400,000 people
M = 300,000,000 mg = 300 kg
Answer:
5.355 g
Explanation:
first you have 30.6 g from ammonium nitrate ( NH4NO3 )
molecular weight for NH4NO3 is 80 g/mole
and molecular weight for nitrogen gas N2 is 14 g/ mole
make this
NH4NO3 --------------> N2
80 g/mol --------------> 14 g/mol
30.6 g ---------------> x
So X = 14 x 30.6 ÷ 80 = 5.355 g of N2
Good Luck
Answer: Q= -34.6 J
Explanation: Use Q= mc∆T
c for solid lead is equal to 0.159 J/g°C
Substitute the values:
=14.8 g(0.159J/g°C)(23.7°C-38.4 °C)
= 14.8 g(0.159J/g°C) ( -14.7°C)
= -34.6 J
Cancel out the following units: g and °C so the remaining unit is in J.
Answer:-
(iv) (i) + (II)
Explanation:-
Hydrogen bonds Occur between Hydrogen and an element with high electronegativity like N or O.
DNA base pairs are arranged such that they are complimentary. Hence hydrogen bonding will occur between both the amide carbonyl and NH2 as well as the amide NH and Nitrogen of the cyclic C=N-C group.
Answer:
545.2
Explanation:
To read a beam balance, you need to add together the numbers that each balance reads.
The first beam reads 500.
The second beam reads 40.
The third beam reads 5.2.
500 + 40 + 5.2 = 545.2
The total mass of the rock sample is 545.2.
