Answer:
1.6666 g/mol = 1 
g/mol
Explanation:
Molar mass of NaOH= 23+16+1 =40g/mol
Mols in 15g = 15/40 mol
If this was dissolved in 225ml of water molarity of the solution is
÷ 225 x 1000 = 1.6666 g/mol = 1 g/mol
Answer:
The formula and value to this question is "=A1+A3+A4+A5 with value 100"
Explanation:
The explanation of the given question as follows:
- In question, it is defined that four cells that are "A1, A2, A3, and A4" contains value that are "10, 20, 30, and 40".
- To add these values we use addition formula that is "=A1+A2+A3+A4". it will give value 100.
- If the user inserts a new row that is "A2" and assigns a value in the cell that is "50" so, we use the above formula that adds values with these values we also use the value "100".
Answer:
// program in C++.
// headres
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// array
int temperatures[7];
// count variable
int count=0;
cout<<"Enter the temperature of all days:";
for(int a=0;a<7;a++)
{
// read temperature of 7 days
cin>>temperatures[a];
// find temperature is extreme or not
if(temperatures[a]<-10||temperatures[a]>25)
// count
count++;
}
// print count of extreme temperature
cout<<"number of days of extreme temperature:"<<count<<endl;
return 0;
}
Explanation:
Create an array of size 7 to store the temperature of all days of week.Read the temperature of each day.If the temperature is less than -10 or greater than 25 then increment the count.This will count the number of days of extreme temperature.Print the count.
Output:
Enter the temperature of all days:-20 12 18 30 32 -15 15
number of days of extreme temperature:4
Answer:
3% inflation rise. No correct cpi option
Explanation:
Consumer Price Index(CPI) is calculated by the Bureau of Economic Analysis and Statistics of a country monthly and annually.
Consumer Price Index(CPI) is used for measuring the changes in the price level of consumer goods and services purchased by households.
Calculating the consumer price index; price in 1964= $1.25, today price= $5.0.
Therefore, consumer price index= Price in today- price in 1964÷ price in 1964,.
Consumer Price index(CPI)= $(5-1.25)/1.25 = 3.75/1.25 = 3 Percent price inflation rise.
For the first cpi; 112-80/80= 0.4 percent( not equal to the 3 Percent inflation rise).
For the second cpi: 141.6-60/60= 1.36 Percent inflation rise(not equal to the 3 Percent inflation rise).
For the third CPI: 126.4-75/75 =0.68 percent inflation rise[not equal to the 3 Percent inflation rise].
For the third CPI: 108.5-90/90=0.21 percent inflation rise(not equal to 3 Percent inflation rise)
Therefore, none of the options are right.
Answer:
it would be the first one because it's the header and that's what applies
