利用给定的质量和体积
求出溶液的浓度
给定代表溶质质量和溶液体积的两个值 M 和 V ，任务是计算溶液的浓度。 例:
输入: M = 100.00，V = 500.00 输出: 200 解释: C = 1000 * (100 / 500) 溶液浓度为 200 输入: M = 1.00 V = 1000.00 输出: 1
方法:溶液的浓度定义为每升溶液中溶质的质量(克)。 数学上:
C = 1000 * (M / V) 其中 M =溶质质量，V =溶液体积。
因此，为了解决问题，请遵循以下步骤:
- 使用公式 C = 1000* (M / V) 计算溶液浓度。
- 打印结果。
以下是上述方法的实现:
C++
// C++ program to find
// concentration of a solution
// using given Mass and Volume
#include <bits/stdc++.h>
using namespace std;
// Function to calculate
// concentration from the
// given mass of solute and
// volume of a solution
double get_concentration(double mass,
double volume)
{
if (volume == 0)
return -1;
else
return (mass / volume)
* 1000;
}
// Driver Program
int main()
{
double mass, volume;
mass = 100.00;
volume = 500.00;
cout << get_concentration(mass,
volume);
return 0;
}
Java 语言(一种计算机语言，尤用于创建网站)
// Java program to find concentration

// and Volume
class GFG{
// Function to calculate
// concentration from the
// given mass of solute and
// volume of a solution
static double get_concentration(double mass,
double volume)
{
if (volume == 0)
return -1;
else
return (mass / volume) * 1000;
}
// Driver code
public static void main(String[] args)
{
double mass, volume;
mass = 100.00;
volume = 500.00;
System.out.println(get_concentration(mass,
volume));
}
}
