使用说明与常见问题How-to & FAQ

「克转摩尔」是什么？What is the Grams to Moles Calculator tool?

n = m / M。可设置「质量 g」、「摩尔质量 g/mol」。n = m / M. Settings: Mass g, Molar mass g/mol.

如何使用「克转摩尔」？How do I use the Grams to Moles Calculator tool?

在「克转摩尔」中，填写「质量 g」、「摩尔质量 g/mol」等参数，结果会随输入实时计算并显示在下方。In the Grams to Moles Calculator: Fill in "Mass g", "Molar mass g/mol"; results are recalculated instantly as you type.

水的摩尔质量是多少？What is the molar mass of water?

H₂O ≈ 18.015 g/mol（2 × 1.008 + 15.999）。所以 18 g 水约 1 mol。本页按 n = m ÷ M 计算，其他物质请填它的摩尔质量。H₂O ≈ 18.015 g/mol (2 × 1.008 + 15.999), so 18 g of water is about 1 mol. The page uses n = m ÷ M; for other substances enter their molar mass.

能举个计算实例吗？Can you show a worked example?

例如在「克转摩尔」中填 质量 g = 18，摩尔质量 g/mol = 18.015，结果区显示：物质的量：0.999167 mol；分子数约：6.017×10²³For example, entering Mass g = 18, Molar mass g/mol = 18.015 in the Grams to Moles Calculator gives: Amount of substance: 0.999167 mol; Molecules (approx.): 6.017×10²³

哪些输入会被检查？Which inputs are validated?

「克转摩尔」会检查这些输入——「质量 g」、「摩尔质量 g/mol」：必须填写，须大于 0；绝对值超过 10¹⁵ 的数也会被拒绝。不符合时结果区显示具体提示，不会给出数字。The Grams to Moles Calculator checks its inputs — "Mass g", "Molar mass g/mol": required, must be greater than 0; numbers above 10¹⁵ in absolute value are rejected too. When a value fails, the result area names the problem instead of showing a number.

有哪些选项可以调整？What options can I adjust?

「克转摩尔」的设置：「质量 g」默认 18；「摩尔质量 g/mol」默认 18.015。每次生成结果都按当前设置处理。Settings in the Grams to Moles Calculator — "Mass g" default 18; "Molar mass g/mol" default 18.015. The result always uses the current settings.

计算结果可以用于作业或工程吗？Can I use the results for homework or engineering?

「克转摩尔」使用教科书标准公式（公式写在说明和常见问题中），适合学习和估算核对；涉及安全的工程设计请以规范和实测为准。The Grams to Moles Calculator uses standard textbook formulas (given in the description and FAQ), which is good for learning and checking estimates; for safety-critical engineering follow codes and measured values.
