Answer:
// Program is written in C++ Programming Language
// Comments are used for explanatory purpose
// Program Starts here
#include<iostream>
using namespace std;
int main ()
{
// Declare Variables
int quarter, dimes, nickel, cent;
// Enter values for each
cout<<"Quarter: ";
cin>>quarter;
cout<<"Dimes: ";
cin>>dimes;
cout<<"Nickels: ";
cin>>nickel;
/*
In the United States, these coins have the following values
Quarter = 25 cents
Done = 10 cents
Nickel = 5 cent
Total cent is calculated below
*/
cent = 25 * quarter + 10 * dimes + 5 * nickel;
// Print Total
cout<<"The coins are worth "<<cent<<" cents";
return 0;
}
The 2nd energy level can hold a maximum of 8 electrons.
Answer:
5.52atm
Explanation:
Using the pressure law formula:
P1/T1 = P2/T2
Where;
P1 = initial pressure (atm)
P2 = final pressure (atm)
T1 = initial temperature (K)
T2 = final temperature (K)
According to the question, the following information were provided;
P1 = 4.72 atm
P2 = ?
T1 = -3.50°C = -3.50 + 273 = 269.5K
T2 = 42°C = 42 + 273 = 315K
Using P1/T1 = P2/T2
4.72/269.5 = P2/315
CROSS MULTIPLY
4.72 × 315 = 269.5 × P2
1,486.8 = 269.5P2
P2 = 1,486.8 ÷ 269.5
P2 = 5.52atm
Answer:
0.2598 M
Explanation:
Molarity is mol/L, so we have to convert the grams to moles and the mL to L. To convert between grams and moles you need the molar mass of the compound, which is 36.46g/mol.
Round to the lowest number of significant figures = 0.2598 M
